1. A dangerous toxic pollutant has been accidentally spilled in a lake. t = e4 The speed of water contamination is modelled by P(t): where P is the concentration in mg per m³ and t is time in minutes. 40 minutes later, the Environment Protection Agency has released in the la another chemical that neutralizes the toxic pollutant. The concentration of t second chemical is modelled by N(t) = 31 The toxic pollutant will b completely neutralized when the two concentrations are equal. a) When is the maximum concentration of pollution reached? b) When is the toxic pollutant completely neutralized?
